TO ALL WHOM IT MAY CONCERN: y

-Be it 'known that'L CHARLEs'NOETHLICH, of Muscatinefin the county of Muscatine, and' State of Iowa, have invented a new and improved Wagon-Lock and Ido hereby declare that the following is a full, clear,and exact description thereof, reference being had 'to the accompanying drawings, making u. p art of this specification, in whieh-' l y l i' Figure 1 is a. side elevation ofthe improved' wagon-lock with its leve'rlocked.-

vFigure 2 is a similar view of the same parts unlocked.

Similailetters of reference indicate corresponding purtsin both'figures. i v

This invention relates to a new and improved device which is designedmorepiirticularly for operating the brake of :i wagon, but which may be .Auserlto advantage foiother purposes.

The nature of' my invention consistslin applying to tho 'hnd-leverwhich is connected to the brake-bar-of n. egon-brake, a .locking-lever and pm vh'nnd also a segmentnlmnek or ratchet, :ill of which are so constructed Ythat while n person een with' one lmnd disongage said p irwl from the segmental ratchet, audvibrate the'brakelever, he con also ci'igagetheL-piiwl with this segmentnl rntehct, and lock it in place, So that thebrake-le'ver cannot be casually movedoutofthe position'in which itwas locked, as will'be hereinafter described- To ennhle Vothersskilled in the art to understandmy invention, I will describe its construction and operation.'

'In ille flcwmfpanylng'drawings, A represents a segmental ratchet-bar, which is securedv rigidly to the side of a. wagon, and set'off therefrom a short distance, so as to ndord space forrworking a'lever, B. This ratchet or rack is concentric 4to thcnxis of motion of the hand-lever B, which is pivoted at g to a plate, -@,seoured irynly to the wagon below the segment,.as shown in figs. 1 and 2,

Lever B extendsnp oo the innerside ofthe sevment A. above this se ment to n convenient -heiufllt for a 9 i A g 1 a person slttlng upon the seat of the wagon,- and it terminates in a. curved hond or foot-piece, B. The lever B is connected to the toothed segment A.- by means of a staple, a, whicl1 prevents lateral displacement of this lever, but allows it to /bevibrotcd in a-direction with the length oflsaid segment.

' Dv represents a` puwl, which i's pivoted between the'staple a end' leverB atb, and which is co'nstruetedwith an arm projecting backward and upward, to which'arm arend, F, is'pivoted. The upper end of this vrody F is pivotcd at c, te a link, G, which projectsa hand-piece or lever, G, curved :is shown, sothat when brought in the portions B and G can be grasped by the hand,'and lever B vibreted forward orbackwerdl conta-ct'with the 'curved hond-piece B ofl lever B, as shown inv fig. 2,' it will t closely thereto, so that both of The short' link-'connection -G,.whi`ch is pivoted ut e 15o-the lever-B, and the rod F which connects this link;

to the arm of pawl D, form a' toggle-joint, and o "me'zxns for engaging this pawl with the teeth on'utheuppel edge of the segment A, as Shown in g 1,"nnd for disengaging the 'pawl therefrom a. pleasure.. When the 'arm or lever G of'the link --is moved outward Afrom the'hhdle portion B', as shown in iig. 1, the pawl'D vwill be engaged with one tooth of its segment A, 'and the pivot c will be moved so farbaekof the red line v, that the pawl D will be locked in place, as shown in 6g; 1. In this condition of the parts, lever B cannot be moved either forward or backward. I I' When the lever or crm Gf is brouglit'up against the curved, hand-piece B of A"the lever B, the pivot c will l have swung forward far enough to liftthe nose of'puwl D free from the teeth of the segment A, as shown in' fig. 2, when the lever B may be vibrated forward or backward, and again locked. in any desired position by dropping pawl D. I

I am aware that spring-pawls end connecting-rodsqhavc been used before my invention, in conjunction with brake-levers, but n. spring-pewl, er a pawl whichis held in place by c spring, will allowua lever to be moved forward or in n directionwith thepitch of the teeth'rof the segment-ratchet, and therefore such a contrivance is notsafe zit all times.' n I' By my improvement a moresubstantial device .isfp'roduced 'withoutspri'ngm which 'are always liableto .fail

in their operatiomend a positivel lock can be made, which is-not'liable 'to derangement or accident, and whichv can be readily manipulated, and which, when locked, 'can neither he moved forward norba'ekward.

I do not claim a. wagon-lock `sch as is shown in the patent'of Thomae Ure, dated Mziy 28, 1867 ;`l hilt What I do claim as my invention, and desire to secure by Letters-Patent, is#- tion The arrangement and construction of the angular lover G G', link F, and pivoted pawl D, in combina Vwith the bevel-toothed rackjA, and vibrating-leverB B, the arrangement of the whole bcngrsuch that the pivot c can be thrown tothe ijight or loft of the lin'e `:l: @and when in one Position the pa'wl will be firmly locked without the'aid of an auxiliary stop, and when in the otherrpostipn', the pnwl will be unlocxelh all substantially in the marmer described and shown.
